摘要

The method involves obtaining a fixed frame (2) and a grid (3) by molding the frame and grid in same mold such that the grid is formed in the frame with supports (4) arranged with respect to complementary joints (5) of the frame, in a molding position. The frame and the grid are removed from the mold. The grid is rotated for being mounted on the frame by coinciding with the supports on the joints, in usage position. An independent claim is also included for a closing and covering device.
